COMPENSATOR FOR PIPES.

To all whom 'it may concern:

Be it known that I, JOHANN KoENIe, a subject of the King of Bavaria,residing at 97 Alexanderstrasse, Riga, Russia, have invented new anduseful Improvements in Compensators for Pipes, of which the following isa specification.

For the purpose of compensating for alterations in length of piping aflexible pipe has been connected in the same and relieved of strain bybars jointed to the two connected pipe ends.

According to my invention the intermediate pipe employed to compensatefor the alteration in length of the piping is a rigid pipe, connectedwith the piping by ball and socket joints and capable of expanding orsliding in the direction of its length in a stuffing-box orstufling-boxes presented by the said ball and socket joints.

One form of construction of my invention is illustrated in theaccompanying drawing, the figure being a vertical section through thecompensator.

1 and 2 are the two flanged bends of the piping, connected with eachother in wellknown manner by bars 3, a jointed to them. Theconnecting-pipe 5 is furnished at one end with a ball-piece 6, and atthe other end slides in longitudinal direction in a stuiiing-box 7. Thestuffing-box 7 is connected in any suitable manner to the flange of asecond ball-piece 8, which enables the pipe 5 to turn in the bend 2.

In the particular constructive form of the invention illustrated in thedrawing, the stuffing-boxes 9 constituting the sockets for theball-pieces 6, 8, and the stuffing-box 7 to receive the end of the pipe5, consist of a metallic collar and an annular gland, both exactlyfitting the surface of the ball-pieces 6, 8 and the pipe 5 respectively.Between 7 Specification of Letters Patent.

Application filed February 24, 1908.

Patented Oct. 5, 1909.

Serial No. 417,297.

each collar and its gland a groove is presented, in which a packing-ring12 of asbestos, soft metal or the like, not yielding below a certainpressure, is inserted. To enable this kind of joint to be employed,there is provided around each stuflingbox an annular space 10 into whichthe medium flowing through the piping, such as hot steam or cold water,can enter. Naturally, however, any suitable construction of stuflingboxmay be employed, without departure from the essential features of theinvention. Any water of condensation collecting in the space 10 at thetop, can be run off by the provision of a suitable flexible pipe 11 ofmetallic hose, or the like.

Having thus described my invention, what I claim as new is In acompensating device for piping, two flanged bends, means pivotallyuniting the same, a connecting pipe having at one end a ball piece, astufling box carried by one of said bends and forming the socket forsaid ball piece, there being an annular space around the stufiing box, astuffing box in the other bend, a ball piece therein with an annularspace around the stuffing box, a stufiing box in the inner end of thelast-mentioned stuffing box with an annular space therearound, the otherend of said pipe being longitudinally received in the last-mentionedstuffing box, and means for drawing off the water of condensationcollecting in the said annular spaces.

In witness whereof I have hereunto signed my name this 23/5th day ofFebruary 1908, in the presence of two subscribing witnesses.

JOHANN KOENIG.
